Monochromatic light of frequency f1 is incident on a photocell and the stopping potential is found to be V1. What is the new stopping potential of the cell if it is radiated by monochromatic light of frequency f2 ?
\[V_{1}-\frac{h}{e}\left( f_{2}-f_{1} \right)\]
\[V_{1}+\frac{h}{e}\left( f_{2}+f_{1} \right)\]
\[V_{1}-\frac{h}{e}\left( f_{2}+f_{1} \right)\]
\[V_{1}+\frac{h}{e}\left( f_{2}-f_{1} \right)\]
